Be it known that I, BERNARD MULLER- THYM, a citizenof `the United States, and resident of Kansas City, in the countyy of Jackson and State of Missouri, have invented a certain new and useful improvement in lloriZontal-VVick Burners, of Awhich the following is a complete specification.

kThis invention relates to burners i of that class exemplified in my Patent No. 1335011, dated March 30, 1920, in which a long flexible wick is drawn through a body of oil yand,

wound upon a slowly turning drum or arbor, the llame being supported on the wick at an intermediate point, i. e., at the surface of thebody of oil. y

Sanctuary' lights are so-called perpetual lights but are in fact merely temporary and burn at most but for a few days at a time, the consumption of the wick or thekoil resulting in extinguishment of the light. Sanctuary lamps of the type mentioned in the patent above identified, have been operA ated continuously for three or four weeks without attention, but such lamps l have found not fully satisfactory because they F or sanctuary lamps, the small size ofthe jflame is unobjectionable, in fact is desirable, but such a structure for producing light and heat, is inadequate. yVlith a vertical wick of the type shown by said patent, the oil is absorbed to the highest point of the flame where the oxygen of the air combines with the gases produced by thedecomposition of the oil, and the flame does not effectively reach such gases and hence imperfect combustion occurs. y

A vertical wick is also 'objectionable because the ytransformation rvof the oil to gas will result in the deposit of noirconsumable matter on the wick which ultimately will destroy the capillary properties thereof. The objections raised to the vertical type of wick of course do not apply particularly to candles', as in a candle the wick as soon as relieved of'its support by the tallow or wax, will bend to a point at one side ofthe llame where the white part thereof will burn the deposits or carbone, and the wick is suppliedto the flame' in fresh conditloncontinuously by the consumption or burning away of the body of tallow or wax, f

VI haveV found that by using a wick horizontally at the pointwhere it is to burn, n o

oil is fed to the flame exceptin the lowery y the widthof the flame yand struction shown byFigure l.

part `thereof so that the ascending gases generated at such point are notjinterfered with and readily mix with 'theL oxygen of thek air. ln this type of wick, it is preferable to provide the body of cotton or, other kconsumable material, with a thin flexible non-` consumable core.y yThis wick is fed endwise by automatic mechanism, such as a clockwork, and the speed of traveljdetermines hence the yvolume of light zand heat produced thereby. In this construction the deposit of carbon will stop the flow or advance of oil `in the wick and thus give the outer or advanced part vof the flame 'an opportunity to burn suclrdeposit if the wick is of a non-combustiblenature. On the other "hand if it is of acombustible nature the body of the wick will burncompletely from" the core@k The invention also comprises a guard for setting` up a circula# tion of air forwardly thus limitcthe width of the flame by preventing kthe same backing up upon the wick,

With ythe general object in view of pro,- ducing va kburner forproducing a so-called perpetual flame, especially for the sanctuary and in p'laces'diflicult orfinconvenient ofaccess, asin light houses, mountain signal stations and the like,` the invention will now be described by reference to the accompanying drawing which illustrates one `form of construction which I have devised l for embodying the proposed improvement, after which the features therein deemed to be novel will be particularly set forth and claimed.` f f y In the accompanying drawing:

Figure 1 represents a view partly invertical section and partly in side elevation, of a sanctuary lamp embodying the invention, the mechanismyfor operating the wick y and forA supplying the bowl of the lamp withv oil, being located yat the opposite side of a partition from thebowl or body portionkof the lamp itself.

Figure2 is a top plan view of the con- Referring tothe drawingin detail, 1inc'licatespthe bowl of the lamp, the top of toward the `flame and ,y

Lwhich is shown as removable and provided with a tubular guide' 2, vertically 'over a chamberedportion 3 of the bowl.

Located within the chambered portion 3 so as to be capable 'of ,revolving therein is a reel a and wound upon said reel is wick comprising a'fleXible metal core k5 and a body G of cotton or the like covering said core.

7 is a depending tube extending through the guide 2 and provided its upper end with an elbow shaped portion 8, the latter being enlarged and internally threaded at its lower end at 9 where it is screwed to the upper end el tube l and by restingupon the top of the bowl, liorins a support 'lor said portion 7, and the lower end oi the latter is vflared or bell shaped as 1G.

rlhe upper end oit the elbow shaped or curved portion 8 or the tube is disposed horizontally and iitted within and spaced iroin the conical guard ll, prorided with adepending leg l2 secured to the top of the bowl., the iront or reduced ends oi' the tube 8 and the guard ll being disposed vertically over a perilorated depressed portion Llil in he top, so that any oil which ina-y drip ironi. the iront end or the tube and. guard shall pass back into the bowl.

ln open tion the wick is ignited at the i'ront end ot the said tube and guard, and

the body or absorbent portion or' the wick will burn troni the core at such point, the core extending forward to a winding drurn or arbor il arranged vertically and journaled in the sleeve portion l5 tornied on the top the bowl at the inner side thereof. A pulley 16 is mounted on said drum or arbor and is connected by a flexible belt or the like l? to a pulley 18 rotatable with a beveled gear oi a clock work 19 mounted in a suitable casing 2O at the oppositeside of the partition 21 from the bowl. The gearing oit' the clockwork may be driven by an ordinary clock spring, not shown, or by any other suitable power.

Superposed with respect to the clockwork mechanism, is a tank 22 'for containing any required quantity of oil, and providel with a iilling opening 23. At the lower end or the tank is discharge tube 2l leading to the interior or' the bowl, and said pipe is controlled by a suitable valve 25. L second pipe 26 leads from the upper end o'l the tank to the bowl at a point where the oil level inthe latter is to be maintained, and is controlled by a valve 27. lt will be understood that the oil leeds by gravity to the bowl and that as soon as its level covers the connected end of the pipe 26, the feeding operation stops, and that as consumption lowers said level slightly, thesupply from the tank is iininediately replenished through the pipe 2l.

Assuming that the parts are arranged as shown and that the clock work is in operation` and feeding the wick slowly in the direction indicatedby the arrow, Figure l, it will be seen that the wick is ignited at the iront end of the guard ll. will burn at such point as indicated, it being under- 6 stood that the speed of travel of the wick is ordinarily imperceptible to the eye, and that the absorbent portion ol the wick is cons ined and hence liniits the advance ol the llaine towards the druin or arbor. lt will also be noted that the heat or the llame will up a circulatioii et air through the guard lll and around the tube S toward the Ae and hence guard against the widening` ol the aine toward the tube 8 and tending to keep the wick cool adjacent the flame.

The tube not only serves as a guide tor the wick but tends to assist the capillary action especially when heavy oil is used, and also to prevent the wick `troni being charged with an quantity or" oil, any drippage however, which may occur at the 'liront end oit tube S dropping rdown upon the p .iorated sunken portion l of the top and passing back into the bowl. lVith a burner oit 'lois character the speed ol trarol el the wick will determine the width oi the haine and hence the volume ol' light and heat generated and it will be -understood iat when inade ot large size and used with proper vlectora, the light inay be einployed tor signal purposes or the like and that the length of the wick and the continuance ot its feeding nioveinents are the 'factors which deterinine how long the light inay be maintained without attention on the part of those incharge.

lt will be noted that by producing the tlaine on a horizontal portion of the wick, and imparting niovenient to the latter, the .vidth of the ilaine cannot only be controlled but that oil is Yled to the llame only at the lower part thereof so that the gases produced at such points ascend without interterence and are thereiore mixed with the oxygen olf the air to produce perfect conibustion. .t will also be understood that any solid deposits or carbons lett in the wick will not stop the flow of the oil as at the outer part of the thune such deposits will burn oil it the wick is ol a non-coinbustible nature. lli' the body of the wick however, is ol a combustible material, such cotton, such body will burn oil completely and leave the core toftravel to and wind upon the drinn or arbor, as indicated by Figure l.

liroiu the above description it will be apparent that l hare produced a burner embodying the features of advantage set 'forth as desirable in the statement ot the object of the invention, and which is susceptible of niodilication in various particulars without departing troni the principle ot construction and inode oit operation involved, or from the spirit and scope of the appended claiins.

That l claim is:
